Product image isn't displayed in the Shop, but on the product page itself

Hi Community,

I have a -what I hope to be- simple problem which I have been strougeling with for some time now.

-In the shop it doesn’t show the pictures of the products. In the frame of the product it only says ‘picture xyz.png’

-When clicking on the product -> directed to single product pare -> product picture is displayed.

I just don’t get it.

I also tryed different theems -> no differenc

Thanks for your help!
